Purpose The goal of this study was to characterize and quantify maternal use of decontextualized and contextualized input during mother-child interactions including young children with Down syndrome (DS). Method Participants included 22 mother-child dyads with DS ( = 42.8 months) and 22 mother-child dyads with typical development ( = 44.0 months). Parent-child language samples were collected during free-play, book reading, and snack time, and coded for maternal decontextualized (i.e., pretend, explanatory, and narrative talk) and contextualized input (i.e., descriptions, conversation, praise, questions, and directives). Results Mothers of children with DS used a larger proportion of pretend talk compared to other types of decontextualized input and also used a larger proportion of questions, conversation, and descriptions compared to other types of contextualized language. Mothers of children with DS generally used a smaller proportion of decontextualized input compared to mothers of children with typical development, with the exception of pretend talk. Maternal decontextualized input was not related to children's age or language ability in DS. Conclusions Findings shed new light on the early language environments of children with DS, providing important insight into the ways that mothers of children with DS are incorporating decontextualized and contextualized talk into early mother-child conversations. Additional implications and future directions are discussed.
目的 本研究旨在描述和量化母亲在与孩子的互动中使用非语境化和语境化输入的情况,包括患有唐氏综合征(DS)的幼儿。
方法 参与者包括 22 对患有 DS 的母婴 dyad( = 42.8 个月)和 22 对具有典型发育的母婴 dyad( = 44.0 个月)。在自由游戏、阅读书籍和吃零食期间收集了亲子语言样本,并对母亲的非语境化输入(即假装、解释和叙事谈话)和语境化输入(即描述、对话、表扬、问题和指令)进行了编码。
结果 与其他类型的非语境化输入相比,患有 DS 的儿童的母亲使用了更大比例的假装谈话,与其他类型的语境化语言相比,患有 DS 的儿童的母亲也使用了更大比例的问题、对话和描述。与具有典型发育的儿童的母亲相比,患有 DS 的儿童的母亲通常使用的非语境化输入比例较小,但假装谈话除外。母亲的非语境化输入与 DS 儿童的年龄或语言能力无关。
结论 研究结果为 DS 儿童的早期语言环境提供了新的视角,为了解 DS 儿童的母亲如何将非语境化和语境化的语言融入早期的亲子对话提供了重要的见解。讨论了其他的影响和未来的方向。
